ObjectiveTo investigate the relationship between carotid atherosclerosis and progressing stroke.Methods103 patients with acute cerebral infarction within the first 24 hours from onset were tested with carotid color doppler ultrasonography during the first week from admission. Univariate and multiple logistic regression analyses were performed to examine the relationship between carotid intima media thickness (IMT), plaque structure, the degree of artery stenosis and the early deterioration of cerebral infarction.ResultsPrevalence of carotid plaque and thickness of IMT in patients with progressing stroke were higher than that in non progressing patients. In logistic regression, presence of carotid plaque was independent predictors of progressing stroke. Plaque size, extent of artery stenosis and IMT were not included in the regression model.ConclusionPlaque structure and its chemical feature may be the cause of progressing stroke.
5.Classification and evolutionary analysis of pollen allergens
Chinese Journal of Microbiology and Immunology 2010;30(1):56-59
Objective To classify all the plant pollen allergens, each allergen sequence available was compared with protein family database. After that, the appearance and taxonomic distribution of each protein family could be known. When made reference to evolutionary analysis, a regular rule of the distribu-tion of all plant pollen allergens could be concluded. Methods Protein family memberships of each allergen were assigned by comparing the sequences with the Pfam database. Representative members of the most a-bundant pollen allergen families were compared with the Uniprot database using the BLAST server. Acces-sion number of all the interesting homologous could be obtained and all the sequence information could be ac-quired by Batch Entrez. Finally, the evolutionary trees were drawn with the help of MEGA4.0 software. Re-sults One hundred and sixty-eight pollen allergens were classified into 26 protein families. Profilins, pollen _allerg_1 and EF hands constituted the most abundant pollen allergen families. Profilins and EF hands oc-curred in almost all allergenic plant families, whereas allergenic Expansins, FAD_binding proteins, Amb_V allergens and Thaumatins were confined to single taxon. Conclusion It is concluded that the highly con-served sequences of allergens families such as Profilin may be one of the most important reasons of the cross reactivities in allergic diseases. The classification of pollen allergens may be helpful to clinical practice and basic research.

Chinese Journal of Ocular Fundus Diseases 2001;17(1):37-40
Objective To evaluate the effects of cold provocation on optic dise blood flow and retinal light sensitivity of primary open-angle glaucoma (POAG) patients,and explore the relationship between the changes of optic disc blood flow and retinal light sensitivity. Methods A total 33 POAG patients (33 eyes) and 13 normal controls (13 eyes) were tested by using the Heidelberg retinal flowmetry (HRF) and Topcon automatic perimeter,and the optic disc blood flow and retinal light sensitivity of POAG patients and normal controls were measured at normal conditions and after cold provocation. Results The mean optic disc blood flow,volume and the mean retinal light sensitivity of POAG patients decreased significantly (P<0.05) after cold provocation.There was a linear and significant relationship between the decrease of mean optic disc blood flow and mean retinal light sensitivity of POAG patients (r=0.615,P<0.001).The optic disc blood flow of POAG patients with a history of migraine were more likely to reduce in response to cold provocation and reduced much more than those without such history (P<0.05). Conclusion Cold provocation can significantly reduce both the optic disc blood flow and retinal light sensitivity in POAG patients.A close correlation was found between the amount of mean optic disc blood flow decrease and the volume of mean retinal light sensitivity decline.

At the same time, nosocomial infection due to indwelling catheter and the irrational use of antibiotics led to higher rates of infection, 19.23%and 17.69%, there were significant differences. In addition, we could see from the age of nosocomial infection, ≤ 3-year-old children and elderly patients ≥ 60 years old had higher infection rate, 9.43% and 9.71%, there were significant differences. Conclusions According to elements features of infectious disease outbreak in hospital ward, to take effective care and prevention measures to reduce the infectious diseases room of the hospital infection will be of great clinical significance.
9.Expression and clinical significance of matrix metailoproteinase-13 and insulin-like growth factor-1 in the synovial lesion of Kashin-Beck disease
Chinese Journal of Rheumatology 2010;14(10):690-693
Objective To discuss the matrix metalloproteinase ( MMP- 13 ) and insulin-like growth factor (IGF)-1 in knee osteoarthritis (OA) and Kashin-Beck disease (KBD) and to explore the mechanism of synovial lesions and their similarities and differences are compared. Methods Synovial fluid of 18 OA patients, 13 KBD patients, 6 normal controls were collected and their synovium were obtained at the same time.The synovium MMP-13 and IGF-1 were examined by immunohistochemistry, while those of the synovial fluid were tested by enzyme-linked immunosorbent assay (ELISA). One way ANOVA and LSD-t test were used for statistical analysis. Results The results of these 37 synovial tissue and synovial fluid samples showed that: ① The average optical density of the positive staining of the KBD synovial tissue (692±131,354±101, 415±62) was not statistically significant from that of the OA group (452±57, 366±65, 652±86)(P>0.05) and the control group (541±98, 524±202, 379±94, P<0.05). ②There was significant different between the expression of IGF-1 of synovial tissue in the KBD group (311±174, 235±95, 412±109) and the OA group (452±57, 652±75, 544±64) as well as the control group (251±29, 336±54, 388±76)(P<0.05).③ Compared with the concentration of MMP-13 in the synovial fluid of the OA group (0.93±0.51), there was no significant difference between the OA and the KBD group (2.02±1.12) (P>0.05); but, there was significant differences when compared with the control group (2.33 ±0.29, P<0.05). ④ When compared the the concentration of IGF-1 in the synovial fluid in the KBD group [ (2.87±1.48) and the OA group (1.27±0.33)as well as that of the eontrol group (0.93±1.07)] the difference was significant. Conclusions ① Cartilagedegeneration and joint damage may be a part of the articular synovial lesions in KBD patients, just like that of the OA, and the may exist as a part of the pathogenesis. ② MMP-13 may be involved in the synovial damage,and is the major degenerating factors in cartilage extracellular matrix (ECM) in OA patients and KBD patients. ③ As one of the ECM synthesis factors, IGF-1 may play an important role in the synovial damage of OA and KBD disease, but the repair mechanism may be different between the two diseases.
10.Effects of simvastatin on the remodeling in rapid atrial pacing in rabbits
Acta Universitatis Medicinalis Anhui 2014;(2):198-201
Objective In this research we established rapid atrial pacing rabbit models, to investigate the effects of simvastatin on changes of early atrial effective refractory period (AERP) and protein expression of atrial α1c sub-unit of L-type calcium channel on atrial remodeling. Methods 42 rabbits were randomly divided into 3 groups:control group,rapid pacing group and simvastatin group,simvastatin 5 mg/( kg·d) was given intragastrically daily for two weeks before electrophysiology study in simvastatin group, normal saline was given intragastrically in control and rapid pacing group instead. Control group with no pacing, in simvastatin group and rapid pacing group, right atrium was paced at 800 beats/min for 8 hours to establish acute atrial fibrillation models, right atrial effective re-fractory period(AERP)was measured at the basic cycle length of 200 ms and 150 ms before pacing and 1,2,4,6, and 8 hours after the onset of the pacing, the changes of rate adaptation of AERP (AERP200-AERP150) were ana-lyzed . Right atrium tissue was obtained for measurement of protein expression of atrialα1 c subunit of L-type calcium channel by Western blot. Simultaneously,lipid levels in each group was examined. Results No significant differ-ence in lipid levels among three groups was observed. The AERP was shortened and the rate adaptation of AERP (AERP200-AERP150) disappeared during pacing compared with those before pacing(P<0.05). The shortening of AERP was reversed and AERP200-AERP150 was maintained in simvastatin group. Compared with the control group,the protein expression levels of atrial α1c subunit of L-type calcium channel decreased significantly after 8 hours pacing in rapid pacing group(P<0.01). The protein expression levels of simvastatin group decreased insig-nificantly . Conclusion Atrial rapid pacing can induce the shortening of the AERP and the losing of adaptability to the frequency of AERP,pretreatment with simvastatin can improve the degree significantly and maintain the adapta-bility to frequence basically. The protein expression levels of atrial α1c subunit of L-type calcium channel de-creased significantly after 8 hours pacing,pretreatment with simvastatin can prevent this change without lowering the lipid levels,thus contributing to the ionic mechanism of simvastatin for antiarrhythmia.
